Question
The equation $y=0.15 \sin 5 x \cos 300 t$, describes a stationary wave. The wavelength of the stationary wave is[MP PMT 1995](a) Zero meter(b) $1.256$ meter(c) $2.512$ meter(d) $0.628$ meter
Step 1
15 \sin 5 x \cos 300 t$. A stationary wave is formed when two waves of opposite directions are superposed. Let's denote the first wave as $y_1 = a \sin (\omega t - kx)$ and the second wave as $y_2 = a \sin (\omega t + kx)$. Show more…

The equation of a wave travelling in a string can be written as $y=3 \cos \pi(100 t-x)$ Its wavelength is [MP PMT 1991, 94, 97; MNR 1985] (a) $100 \mathrm{~cm}$ (b) $2 \mathrm{~cm}$ (c) $5 \mathrm{~cm}$ (d) None of these
A sinusoidal wave on a string is described by the equation $$y=(0.15 \mathrm{m}) \sin (0.80 x-50 t)$$ where $x$ and $y$ are in meters and $t$ is in seconds. If the mass per unit length of this string is $12.0 \mathrm{g} / \mathrm{m},$ determine (a) the speed of the wave, (b) the wavelength, (c) the frequency, and (d) the power transmitted to the wave.
